Kilian Jornet Announces Bold New Ultra-Endurance Challenge

Kilian Jornet, widely regarded as the greatest endurance athlete of all time, has unveiled his most audacious project yet—combining the grit of the Tour de France with the relentless grind of marathon running.

The mountain-running icon plans to summit every 14,000-foot peak in the contiguous United States, linking them all by bicycle and on foot. His concept blends cycling stages on par with the Tour de France and running a marathon each day, all while climbing some of the highest mountains in America.

A New Level of Endurance

Jornet has long redefined the limits of human performance. From setting speed records on Mont Blanc, Everest, and the Matterhorn, to dominating ultramarathons around the globe, his career has blurred the line between mountaineering, cycling, and distance running.

This latest challenge pushes even further—requiring not just peak physical conditioning, but also careful logistics, recovery, and resilience in some of the toughest terrains on earth.

Why This Challenge Matters

The project is more than just an athletic quest. By connecting summits, marathons, and cycling stages into one continuous journey, Jornet is symbolically uniting three of endurance sport’s greatest disciplines. His effort will not only test human possibility but also inspire runners, cyclists, and climbers to think beyond conventional limits.

As Jornet himself has often said, his greatest motivation comes from curiosity—asking what lies beyond the next climb, the next trail, or the next idea of what’s possible.

The Road Ahead

No specific launch date has yet been set, but anticipation across the endurance community is already high. If Jornet succeeds, this could go down as one of the most ambitious endurance projects in modern history—an odyssey across mountains, roads, and trails that only someone like Kilian could attempt.
